To all whom it may concern:

Be it known that I, ALFRED J. ANDERSON, a citizen of the United States,residing at Wylie, in the county of Red Lake, State of Minnesota, haveinvented certain. new and useful Improvements in Churns andI do herebydeclare the following to be a full, clear,

and exact description of the invention, such as will enable othersskilled in the art to which pointed out in the appended claim, itbeingunderstood that changes in the form, proportion, size, and minordetails may be made within the scope of the claim without departing fromthe spirit or sacrificing any of the advantages of the presentinvention.

In the accompanying drawings,'Figure 1 is a vertical sectlonal viewillustrating'my inventlon.

Fig. 2 is a detail perspective view of one of the elements forming twodashers of a set of the latter. view of one set of dashers.

Referring now more particularly to, the accompanying drawings, thereference characterl designates the body of the churn, having ajournal-bearing 2 arranged centrally and upon the inner surface of itsbottom for the reception of the lower end of the dasher-shaft 3, whoseupper end passes through a bushing 4 in the cover 5 and is fixedlysecured to the latter in any suitable manner, there being a pinionsecured to the bushing 4 and arranged or rotation upon the outer face ofthe cover 5. It will be seen thatthe upper end of the bushing has alaterally-directed flange 6, between which and the upper surface of thecover 5 the inion rotates in amanner to be hereinafter ffllly explained.

Fixedly secured upon the top of the cover 5 is a V-shaped bracket 7,having alining per-- forations 8 for the reception of a revoluble shaft9, provided at its free end with a crankv Specification of LettersPatent.

Application filed June 1, 1905. 'Seria1N0. 2 63,278.

Fig. is a top plan wheel, 10 and having a gear-wheel 11 fixedly securedto its opposite end for mesh with the pinion- 6 of the dasher-shaft 3. 7

From the foregoing it will be readily seen that by grasping the handle12' of the crankwheel 10 the shaft'9 will rotate the gearwheel v1 1,which is in mesh'with the pinion 6,

to rotate the dasher-shaft 3', and reference to the drawings willdisclose that this shaft is provided with a series of shoulders 13-, 14,and 1 5, resultingin the formation of a dasher-shaft of greatercross-sectional diameter in steps toward its lower end. 7

Four dashers are arranged u on each shoulder 13, 14, and 15, the dasherseing of peculiar formation. In other words, two elements compose thefour dashers, the said elements crossing each other at their oint ofintersection with the dasher-sha t. It will be seen that one of theseelements 16 has its op- Patented.1)ec. 5, 1965 a posite ends enlarged,forming the oppositelydisposed dasher-blades 17,. provided withperforations 18, the said blades being bent at a direct right angle tothe plane of the intermediate portion 19 of the member from which theyare formed, thesaid intermediate portion 19 being provided with arectangular opening 20, whereby the element of which the blades areformed may be fitted upon the shaft, which latter is referablyrectangular in cross-section. It wi 1 be seen, too, that theintermediate portions of each element form ing the blades cross eachother, resulting in one being dis osed directly upon the other at theirreduce intermediate portions. These 'elements or dashers com rise oneset, and it I will be understood that t ere is a set of dashers, such asthose described, disposed upon each of the shoulders 13, 14, and 15. Ifdesired, a small pin or other suitable element 21 may pierce thedasher-shaft immediately above the other element forming the-dashers, soas to prevent longitudinal movement of the latter along the shaft. Ofcourse the trunnion 22 at the lower end of the dashershaft 3 is arrangedcentrally ofthe latter and is of just slifiicient length -to'hold thelower end .face of the dasher immediately-above the journal-bearing'2.

By reason of my peculiar formatlon of dashers the cream is turnedupwardly through centrifugal force, causing a rapid progress in IOO thechurning of the butter, and reference to the drawings will disclose thatif I desire I may disposea small faucet 23 in the bottom of thechurn-body 1 for the purpose of extracting or withdrawing buttermilkfrom the churn during the churning operation.

It will now be understood from the manner in which I state that thedasher-shaft is operated that the respective sets of dashers fit tightlyupon the shaft in engagement with the corresponding shoulders of thelatter, and when it is desired to remove the dashers and their shaftsfrom the interior of the body 1 it is simply necessary to lift the cover5 from the top of the body, when, by reason of the dasher-shaft beingfixedly secured to the bushing of the cover and upon which thefaucet-pinion is mounted, the shaft may be readily disengaged from itsbearing 2 and easily removed from the body for churning purposes.

W' hat is claimed 1s 7 In a churn, a body, a dasher-shaft journaled insaid body, the shaft having a series of enlargements to form shouldersarranged one above the other, dashers arranged upon the shaft andsupported by the said shoulders, means for operating the shaft and itsdashers, and an outlet at the bottom.

In testimony whereof I aflix my signature in presence of two witnesses.
